title: The endoplasmic reticulum Ca2+ store: a view from the lumen.
abstract: The endoplasmic reticulum (ER) and its specialized subcompartments such as the sarcoplasmic reticulum, is the main dynamic Ca2+ storage compartment of the cell. Key cellular functions are regulated, either directly or indirectly, by the free Ca2+ concentration in the ER. This article discusses the properties of Ca2+ storage in the ER and considers the functions that appear to be regulated by the Ca2+ stores within the ER, both in and around the ER and at a distance from it.
